The pen. l5: in; its main parts consists of a the"- head I9 press; fitsonto the reduced shank 20 of.

The ball 35 isretained in the nose 36 of the tip 29 in known manner. To permit freeflow of the relatively heavy ink, with which the cartridge tube 21 isusually filled, and in order to avoid,

3 therefore, the possible creation of a vacuum within the flexible tube21, a small breather hole 31 may be provided in a plug 38 fitted intothe free end 39 of tube 21. 1

Referring now to Figs. 8, 9 and 10, a pen 45 with three ball-pointedtips 46 is illustrated. The head 41 in this instance is shown as beinthreaded into the barrel 48 at 49. A decorative metal ring 50 may beinserted at the joint l.

The angle arrangement of the tips 46 holdingfthe ball points is similarto that previously described with respect to Figures 1-6.

Instead of a round barrel as shown in Figs. 1' I to 10 inclusive, anyother suitably shaped barrel may be used, such as, for examples, anoctagon barrel 55 or a hexagonal barrel 56 (Figs. lland 12). Theadvantage of using a barrel polygonalmay be made by skilled personswithout departing from the true spirit and scope'of the invention asoutlined in the appended claims.

The word; skew, is used in the claims in the meaning of'having the'axesof the respective ball-carrying tips lying in different planes. 1

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is: I

1. In a ball point pen, a tubular member, 'a'

beveled end portion forming a closure for said member, said portionbeing formed'with a pinrality of inclined sides cash provided with ahole extending perpendicularly thereto and com municating with theinterior of said member,

the axes of said holes being skew with respect to one another and to theaxis of said member, a plurality of ball-carrying tip portions eachpress-fitted into a respective one Of said apertures and having theirball-carrying ends projecting from's'aid end portion, and a plurality oftubes extending within said tubular member and connected tothe otherends of respective tip pore tions, each of said' tip portions having achannel communicating with the interior of a respective tube whereby inkfrom said tube may reach the ball-carrying end of the tip portion. j

2. In a ball point pen, the combination according to claim 1, whereineach of said tubesis filled with ink of difierent color. I

3. In a ball point pen, the combination according to claim 1 wherein theball-carrying end of each tip portion is formed with a shoulder abuttinga' respective inclined side of said end portion, each tube beingflexible and of smaller diameter than the respective aperture to permitindividual withdrawal of each tip portion and tube from said tubularmember.

4. In a ballpoint pen, the combination according to" claim 1, comprisinga plug at the end of each tube remote from said'tip portion, said plug 4being provided with a breather hole to prevent the creation of a vacuumin said tube.

5. In a ball point pen, a tubular member having apertures in an endthereof, a plurality of cartridges mounted in said tubular member eachcomprising a ball-carrying tip and a tube connected therewith adapted tocontain a writing fluid, said cartridges being arranged with the tips inskew relation to eachother. H

:6. In a ball point penile tubular; member having apertures in an endthereof, a plurality of cartridges mountedin said tubular member eachcomprising a ball-carrying tip and a tub connected therewith adapted tocontain a. writing fluid, said cartridges being arranged with the tipsin skew relation to each other and with the axes 1 extending indirections whereby the tubes pass each other freely in the tubularmember.

7. In a ball point pen a tubular member having apertures in an endthereof, a plurality of cartridges mounted 'in said tubular member eachcomprising a ball-carrying tip and a tube connected' therewith adapted.tov contain a writing fluid, said cartridges-beingarranged with the tipsin skew relationto' eachother and having flexible tubes passing eachother freelyin the tubular member."

- 8. In a ball "point pen,

interiorof said member, the axes of saidholes being-skew with respecttoone'another and to' the axis of said member, a plurality of ball-car-.

rying tip. portions seated on said-end at the respective one of saidaperturesand having their from'said tube may reach the ball-carrying endof the tip portion.

9. In a ball point pen,-the' combination according to claim 8, whereinthe ball-carrying end of each tip portion is formed with a shoulderabutting 'a' respective'side of said endportion, each tube beingflexible andiof-smaller' diameter than;

the respective aperture to permit individual'withdrawal of each tipportion and tube from said tubularmember. 1 V
